Application

L-Histidine monohydrochloride monohydrate has been used as a component of broth to match the tuna meat amino acid composition. It has also been used for partial rescue of the IMPL2 (myo-inositol monophosphatase) phenotype during seed development of Arabidopsis.

Biochem/physiol Actions

Histidine takes part in protein methylation. It is associated with the hemoglobin structure and function. Histidine is present in antioxidative dipeptides. It is involved in one-carbon unit metabolism.

Myo-inositol monophosphatase (IMP) catalyzes the dephosphorylation of myo-inositol 3-phosphate in the last step of myo-inositol biosynthesis. IMP is also important in phosphate metabolism and is required for the biosynthesis of cell wall polysaccharides, phytic acid, and phosphatidylinositol. In Arabidopsis, IMP
